I've just gotten one of these Teensy boards: http://www.pjrc.com/store/teensy_pins.html
I am trying to set it up using the basic keyboards tutorial. It is working correctly on Windows PC devices when I plug it in and press one of my buttons the proper key presses come through. But if I plug it into an Android device (Toshiba Thrive) I can tell that it recognizes it as a keyboard because it stops showing me the soft keyboard just as it does if I plug in a usb keyboard. But when I press my buttons no keypresses come through.
Does anyone have experience setting up a teensy board to be recognized as a USB keyboard on Android?
Edit so it turns out that it works if I select USB type "Disk(internal) + Keyboard" But not with "Keyboard + Mouse + Joystick" I now suspect that the inclusion of joystick in this profile is what is causing it not to work. I've read that some android devices do not support input devices with joysticks.
So a followup question would be: Does anyone know how to remove the joystick functionality from the Teensy 2.0 board?
